The skeletal system gives the body its basic framework, providing structure, protection, and movement. The bones in the body also produce blood cells, store important minerals, and release hormones necessary for bodily functions. Unlike other living organs, bones are firm and strong, but they have their own blood, lymphatic vessels, and nerves. Red bone marrow forms most of the blood cells in the body and helps destroy old blood cells. Another type of marrow, yellow bone marrow , resides in the central cavities of long bones.
Paget disease of bone
Major, Medical Corps, U. Army; Major, Medical Corps, U. Tuberculosis of bones and joints must necessarily be considered together. The disease usually originates in bones near joints and the latter become infected at an early stage of the disease. A tuberculous focus may be established in a bone distant from a joint, but this is unusual, and in the joint symptoms lie its chief manifestations and significance. It may be defined as a localized, progressively destructive process, caused by the activity of the tubercle bacillus in the tissues of bones and joints Allison. The only objection to this definition is the use of the word localized, and it would perhaps be safer to add that joint involvement is a local manifestation of a generalized condition.
Bones are an important part of the musculoskeletal system. This article, the first in a two-part series on the skeletal system, reviews the anatomy and physiology of bone. The skeletal system is formed of bones and cartilage, which are connected by ligaments to form a framework for the remainder of the body tissues. This article, the first in a two-part series on the structure and function of the skeletal system, reviews the anatomy and physiology of bone. Understanding the structure and purpose of the bone allows nurses to understand common pathophysiology and consider the most-appropriate steps to improve musculoskeletal health.

Please consult the latest official manual style if you have any questions regarding the format accuracy. Diseases of the bone include non-neoplastic disorders such as genetic defects e. The age of the patient and the location of the tumor are very important considerations in the diagnosis of bone tumors. For example, most chondrosarcomas occur in older adults and almost never occur in the bones of the hands, whereas most Ewing sarcomas occur in the diaphysis of long bones of children. Diseases of the joints include inflammatory and noninflammatory arthritides. The two major types of arthritis are osteoarthritis and rheumatoid arthritis.
Paediatric Pathology pp Cite as. The skeleton is mesenchymal in origin. Most of its components pass through membranous and cartilaginous stages of development before becoming ossified, although in some parts there is only a membranous stage. These processes of endochondral and intramembranous ossification are well described in standard textbooks of histology. A detailed account of normal bone, its development and the structure and function of bone cells is available in Revell
NCBI Bookshelf. Office of the Surgeon General US. The body systems that control the growth and maintenance of the skeleton, which are described in Chapter 2 , can be disrupted in different ways that result in a variety of bone diseases and disorders.
Your bones help you move, give you shape and support your body. They are living tissues that rebuild constantly throughout your life. During childhood and your teens, your body adds new bone faster than it removes old bone. After about age 20, you can lose bone faster than you make bone. To have strong bones when you are young, and to prevent bone loss when you are older, you need to get enough calcium , vitamin D , and exercise. You should also avoid smoking and drinking too much alcohol. Bone Diseases.
Diseases and injuries of bones are major causes of abnormalities of the human skeletal system. Although physical injury, causing fracture, dominates over disease, fracture is but one of several common causes of bone disease, and disease is in fact a common cause of fracture. Bone Diseases Encyclopedia Articles See articles Featured Articles Cervical spondylosis Cervical spondylosis, degenerative disease of the neck vertebrae, causing compression of the spinal cord and cervical nerves. Prolonged degeneration of the cervical spine results in a narrowing of the spaces between vertebrae, forcing intervertebral disks out of place and thus compressing or Osteoporosis Osteoporosis, disease characterized by the thinning of bones, with a consequent tendency to sustain fractures from minor stresses.

Articles in the December issue discuss various health issues affecting school-aged children, including acne, eczema and growth disorders. Volume 41, No. Its aetiology is only partly understood, but includes both genetic and environmental factors. This article outlines the clinical features, diagnosis and management options for Paget disease of bone.
Кольцо? - Он вдруг забеспокоился. Вгляделся в полоску на пальце и пристыжено покраснел. - О Боже, - хмыкнул он, - значит, эта история подтверждается.
Добро пожаловать, цифровой вымогатель. Фонтейн даже глазом не повел. - Каким временем мы располагаем. - У нас есть около часа, - сказал Джабба.
